Title: Organic waste fuel and apparatus for producing the same
Inventor: TAKAO KATSUMI
IPC: B09B3/00
Filed: 1992-01-17
Abstract: PURPOSE:To easily and inexpensively obtain a fuel having a high efficiency of combustion by compression-molding an organic waste, e.g. a kitchen refuse, into a board having many through-holes extending from one to the other side. CONSTITUTION:A cylinder 1 having on its side wall a fine mesh 13 through which only water permeates is provided with a press board 3 in a slidable manner. The board 3 is provided with projections 32 on its pressing side. A perforated board 2 having through-holes 22 penetrable by the projections 32 is disposed opposite to the board 3. An organic waste W, e.g. a kitchen refuse, is put in the cylinder 1 via a tilting passageway 12. The board 3 is forced down to compress the waste W. Simultaneously therewith, the waste W is pierced by the projections 32 to form many through-holes, and the resultant waste liquid is discharged through the mesh 13. Thus, the compression-molded objective fuel is obtained which is in a board form having many through-holes extending from one to the other side.

Title: Speed reduction shock reducing method for car
Inventor: ASAYAMA YOSHIO
IPC: B60W10/10
Filed: 1981-02-25
Abstract: PURPOSE:To reduce the speed reduction shock by blocking the shift-down control signal, during the decelleration of brake, and controlling the rotation of an engine. CONSTITUTION:Under braking operation, the control of engine speed is stopped at the shift down while the engine speed is controlled for predetermined time at the lock-up control then the engine speed and the torque controller output speed are combined to reduce the speed reduction shock. Assuming the gear ratio of the reduction gear is 1.3 while the torque converter output speed at the shift down is 1,300rpm, the engine speed must be brought to 1,690rpm (Curve II) during the speed change time DELTAT in order to prevent the variation of the car speed. While under the speed reduction through the brake operation, the car speed will drop during the time DELTAT (Curve III), thereby the increase of the engine speed will cause the acceleration during the speed change thus to produce the speed change shock. Consequently, in this case, the increase control of the engine speed is stopped.

IPC: G11B7/135
Filed: 1992-02-13
Abstract: PURPOSE:To reduce the size of this optical head by providing a specific polarizing filter and a photodetector whose light receiving region is plurally divided. CONSTITUTION:A polarizing filter 32 has an azimuth of approximately 45 degrees with respect to the E direction of the polarization direction of a light source 30 whose region is divided into quadrisections. A pair of regions diagonally located in the filter 32 have the same azimuth and another pair of diagonally located regions has an azimuth crossed orthogonally to the former. A light spot 34 becomes polarized components having approximately the same light quantity and crossed orthogonally to each other by the filter 32 and the polarized components are made incident on a photodetector 33. Respective dividing lines of the filter 32 and the detector 33 are coincident with each other. Phases of the electrical signals from regions 33a and 33c and the signals from regions 33b and 33d are opposite respectively. Therefore, by taking the sum of the generated signals and taking the difference thereof by a differential amplifier, in-phase noises caused by noises of a light source 33 and reflection unevenness of a disk 13 are canceled, only information signals of the disk are detected with high quality and the size and the weight of the optical head are reduced.

Title: Direct conversion receiver
Inventor: IMURA MINORU
IPC: H04B1/707
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a direct conversion receiver where reception quality is maintained excellently without increasing its power consumption. SOLUTION: ADC offset voltage is produced in an output base band signal of mixers 14a, 14b because of even harmonic distortions of the mixers 14a, 14b. The DC offset voltage is eliminated by capacitors 19a, 19b and the resulting base band signal is given to A/D converters 20a, 20b. Capacitances of the capacitors 19a, 19b are selected so that a cut-off frequency of a high-pass filter consisting of the capacitors 19a, 19b and input resistors of the A/D converters 20a, 20b is about 1% of a symbol rate of QPSK modulation in use or below. Thus, the effect of the DC offset voltage is disregarded without losing reception quality (BER).

Filed: 1996-01-22
Abstract: PROBLEM TO BE SOLVED: To obtain a measuring apparatus by which an output resistance can be measured with high accuracy by installing a threshold voltage source group used to set a voltage which is higher than the output voltage of a device (DUT) to be tested and a threshold voltage source group used to set a lower voltage. SOLUTION: Respective output pins of a DUT 20 are connected to input terminals of a high-speed scanner 16, the high-speed scanner 16 scans voltages of the respective input terminals, and a voltage measuring device 17 reads out their voltage values sequentially. Respective groups of threshold voltage sources VT1's, VT2's at a plurality of programmable loads PL's 20i (where i=1 to m) are installed alternately. In the group of the VT1's, a voltage which is by a definite value higher than the output voltage of the DUT 10 can be set, and a voltage which is a definite voltage lower, can be set at the group of the VT2's. Consequently, a constant load current flows out to the side of the DUT 10 from the PL's at the VT2's, and a constant load current flows into the PL's at the VT2's.  Since the constant load current which is taken into by the DUT 10 and the constant load current which is discharged are of the same quantity, the currents are balanced so as not to interfere.
